Under the current implementation of IRIS Performer, the frame rate is
constrained to be an integer multiple of the video refresh rate. Your
video refresh rate is 72 Hz and so if the simulation is unable to run at
72 Hz, then it will drop down to the next integer multiple of 72, i.e.
72 / 2 = 36 Hz.
